Each of eight bearings in a bearing assembly has
a diameter (in millimeters) that has the pdf
	
	f(x) = 10*x^9 , 0< x < 1; zero otherwise
	
Let Y=max(X1,X2,...,X8) be the maximum diameter. 
Assuming independence, find the CDF and the PDF 
of the maximium of the eight bearings and compute 
P(0.9999 < Y < 1)
